Need help ASAP, HP laptop suddenly stopped booting

So here's the deal, my GF's 3 year old HP laptop, a Pavilion dv6000 series, suddenly stopped booting correctly yesterday, every time it boots, a message appears saying:

"Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:

1. Insert your Windows installation disc and restart your computer.
2. Choose your language settings, and then click "Next".
3. Click "Repair your computer".

If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

File: \windows\system32\config\system

Status: 0x000014c

Info: Windows failed to load because the system registry file is missing, or corrupt."

If I press enter, it then shows the OS I want to load, when I select Windows 7 Home Premium, the same message appears.

Any help would be greatly appreciated.

Thanks.

Have tried Repair your computer?

Boot up using the Startup disk CD or Windows 7 DVD. (not the OEM manufacturer's Recovery Disk) If you have a Netbook, you will need a CD/DVD drive.
Make sure no USB drives are plugged in.

Do a Strartup Repair:
